From January 1922 to August 1939, Methuen (UK) published a version of The Return of the Mucker under the title The Man Without a Soul.

When falsely accused of murder, he flees to San Francisco and is shanghaied aboard a ship.

The ship's secret mission is soon enacted - the hijacking of a specific yacht to take a millionaire's daughter, Barbara Harding, for ransom.

He saves the life of one kidnapper, Theriere, rather than letting him be washed overboard, though he cannot fathom his own reasons.

As he reads about his victory in the papers, he spots a small notice that Barbara's engagement to Mallory has been broken.

Mexico is torn by internal warfare, and they are quickly captured by a bandit general, Pesita.

He hires Billy into his private army, but Bridge has to seek work at a nearby American ranch.

The ranch is owned by Mr. Harding, who has foolishly brought his daughter Barbara to this unstable country, at her insistence, to escape questions about her cancelled marriage.

In the meantime, Billy is sent to case a garrisoned town to plan for Pesita's force to storm and rob the bank.

All assume Bridge robbed the bank, and the foreman plans to turn him over to general Villa, who will hang him.

Barbara pays a shady native, Jose, to take a message to the unknown large American, asking him to aid the imprisoned Bridge.

When Billy learns that Brazos belongs to an unnamed girl Bridge admires, he decided to return the horse regardless of his own safety.

An errand for Pesita stops him at Jose's house, where he is captured by the American foreman and some of Villa's men.

At the border military compound, Billy tells Barbara he won't give her up again, and they plan to leave the country.

Lupoff calls the novel "a most remarkable technical achievement" and states that "In a single book it is virtually a catalog of the pulps."

However, Lupoff ranks The Return of the Mucker less highly (and criticizes it for its negative portrayal of Mexicans) and dismisses The Oakdale Affair as having little to recommend it.
